For missionaries serving in a foreign country, audio-translations from General Conference are a cool idea. I first learned about this when one of my cousins requested some LDS material that would help her with the new language.
You can easily burn a CD of General Conference talks that have been translated into other languages, and this is a great way to help your missionary with the language he is trying to learn.

Holiday-themed packages are among the easiest, and the month of March is no different. A few weeks before St. Patrick’s Day, send your missionary a package full of gold chocolate coins and rainbow skittles. This simple gift will delight the recipient, and requires very little effort on the part of the sender.
